Abstract:
This paper presents the first determination of the spatial
resolution of the ANET Compact Neutron Collimator, obtained with a
measuring campaign at the LENA Mark-II TRIGA reactor in Pavia. This
novel collimator consists of a sequence of collimating and absorbing
channels organised in a chessboard-like geometry. It has a scalable
structure both in length and in the field of view. It is
characterized by an elevated collimation power within a limited
length. Its scalability and compactness are added values with
respect to traditional collimating system. The prototype tested in
this article is composed of 4 concatenated stages, each 100 mm
long, with a channel width of 2.5 mm, delivering a nominal L/D
factor of 160. This measuring campaign illustrates the use of the
ANET collimator and its potential application in neutron imaging for
facilities with small or medium size neutron sources.
